Pristiphora astragali Vikberg, 1978

Pristiphora astragali Vikberg, 1978: 133-137. Holotype ♀ (PR.354VV) in MZH, examined. Type locality: Kilpisjärvi, Finland.

Similar species.

Based on the external morphology, the most similar species are P. confusa , P. opaca , P. pusilla , P. sootryeni , P. staudingeri , and P. subopaca , from which it is best distinguished by the structure of the lancet (Figs 43-44 View Figures 41–45 ). The lancet has weak ctenidia (weak or well-developed in the others) and on the inner surface of the lancet there are small spiny pectines (or dentes semicirculares) that reach the sclerora (present also in P. sootryeni ). However, differences from P. sootryeni (Fig. 45 View Figures 41–45 ) are rather small. Morphologically, the subapical tooth of the claws tends be smaller, the apical serrulae of the lancet are shorter, and the number of ctenidia on the lancet is smaller than in P. sootryeni ( Vikberg 2006). Male unknown.

Genetic data.

Based on a COI barcode sequence of one confidently identified specimen of P. astragali from Abisko (Sweden; DEI-GISHym80042), it belongs to the same BIN cluster as P. sootryeni (BOLD:AAL8292), which in the BOLD database includes two other unidentified specimens from Manitoba, Canada (Fig. 1 View Figure 1 ). The nearest neighbour (BOLD:AAL8277) is 2.40% different. BIN cluster BOLD:AAL8277 includes possibly also P. astragali : in the BOLD database there are two specimens from Manitoba (Canada) and one from Inari (Finland), the latter identified by Matti Viitasaari as " Pristiphora nr. astragali ". Amplification of TPI failed.

Host plants.

Astragalus alpinus L. ( Vikberg 1978; 2006).
